The Samsung N110, a refresh of the best-selling NC10 10-inch netbook, has gone up for pre-order in the US. The N110 (N110-12PBK) has appeared on Buy.com for $441.99 and also at CompSource.com who have it for $450, both are offering free shipping. No actual release date is listed on either site.

Whilst no official release date has been announced, Samsung talks of an April release date in its press release. Therefore it cannot be too much longer before we start to see pre-orders open up on other sites such as Amazon. When keeping an eye out for US pre-orders, you may want to search by the manufacturer part number which is NP-N110-KA01US.

The Samsung N110 (N110-12PBK) looks to improve on the NC10 in a number of ways. It has an expanded touchpad and a higher capacity 6-cell 5900 mAh battery (versus 5200 mAh in the NC10) that should give 9.5 hours of continuous use according to Samsung. The design is also slightly different with a glossy lid with red border. The N110 is powered by a 1.6GHz Atom N270 CPU and 1GB RAM. It also has a 160GB (5,400 rpm) hard-disk drive. It also comes with Wifi (b/g), Bluetooth and Windows XP Home SP3. The official product page still refers to the N110 having a maximum RAM of 1GB but we believe this is a typo.

The Samsung N110 is also expected to appear in Europe in April, although checking a few sites this morning, we have not seen it appear on any of the major sites so far. More news as we have it.
